The territory of the Treveri they entered with all the security naturally felt among allies. But at Divodurum, a town of the Mediomatrici, though they had been received with the most courteous hospitality, a sudden panic mastered them. In a moment they took up arms to massacre an innocent people, not for the sake of plunder, or fired by the lust of spoil, but in a wild frenzy arising from causes so vague that it was very difficult to apply a remedy. Soothed at length by the entreaties of their general[Note 1], they refrained from utterly destroying the town; yet as many as four thousand human beings were slaughtered. Such an alarm was spread through Gaul, that as the army advanced, whole states, headed by their magistrates and with prayers on their lips, came forth to meet it, while the women and children lay prostrate along the roads, and all else that might appease an enemy's fury was offered, though war there was none, to secure the boon of peace.
